It’s been 20 years since Epic Games first released its Unreal game development engine in concert with its first person shooter, Unreal. Since then, the company has been releasing free-to-play games as a loss leader to show off what its powerful development toolkit can do.

Now, with the insane success of Fortnite, the company has flipped the script.

And the company has been plowing that cash back into the community to support esports tournaments with a $100 million prize pool to support competitive Fortnite gamers.

The company’s game has become the kind of old-school cultural phenomenon that one rarely sees in the fractured age of internet silos. It’s inspired dance crazes, Halloween costumes, and even a Monopoly game and a Nerf gun.

And now it appears that the game has also inspired some of the biggest names in Silicon Valley’s venture capital investment scene to commit huge sums to continue its success.
